To, all whom, it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Operating on Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to machines for o)- erating on shoes, and more particularly in mechanism for actuating the pattern cam or other pattern mechanism of machines in part by one of a series of cams 10, arranged which the path of travel of the tool or devices operating on the shoe is determined by a atter-n cam or mechanism.

he invention is designed primarily to improve the pattern cam actuating mechanism of the rounding and channeling Ina chine shown and described in Patent No. 1.030306, dated June 95, 1912, and is illustrated as embodied in that machine. The invention is not confined, however, in its application to this machine, but may be embodied inother forms of rounding and channelingmachines, or in machines for performing other operations upon shoes.

The invention consists of the features of construction and combinations of parts hereinafter described and referred to in the claims, the advantages of which will be obvious to those skilled in the art.

The features of the invention will be readily understood from an inspection of the accompanying drawings, and the following detailed description of the construction illustrated therein.

In the drr wings, Figure l is a side elevation of so much of the rounding and challneling machine of the above patent. as is necessary to illustrate the application of the present invention thereto; Fig. 2 is a side elevation showing the pattern cam actuating and controlling mechanism; Fig. 3 is a detail sectional view on line 33, Fig. .2; Fig. is a detail plan view showing the pawl controlling slides; Fig. 5 is a detail side ele vation of the pawl controlling slides; Fig. 6 is a sectional view on line 6-6, Fig. 4; Figs. 7 and 8 are detail views showing the pawl controlling slides: and Fig. 9 is a detail of the slide operating block.

The machine illustrated is provided with a trimming knife 1, a channel knife block 2 carried in the slide 3,, a crease guide 4,, a feeding jaw 5, and a forepart guide 6. which is carried by an arm 7. The arm extends forward from a, yoke 8 which is pivotally mounted in the frame of the machine and carries a laterally adjustable roll 9, as more ;fully described in the \Vl1.en the forepart guice is moved down into operative position by the operator in atent referred to,

passing from the shank on to the forepart,

. the relative position of the forepart guide and trimming knife is controlled to give the desired outline to the sole about the foreto be engaged by the r51] 9. The pattern cams are carried by a shaft arranged in line with and connected to turn with the sha t l1.

I The cams are intermittently advanced during the operation of the machine, and each cam is shaped to so vary the position of the forepart guide during the rounding opcr'e tion as to give a predetermined contour to the forepart of the shoe sole. in order that the cams may be used in operating upon both right and left shoes, the means for actuating the cams is so constructed that the movements of the cams may be reversed, the cams being driven in one direction while operating upon right shoes, and in the reverse direction while operating upon left shoes, In the construction shown the shaft 11 is actuated to advance the pattern cams through a ratchet wheel 12 secured to the lower end of a shaft 13 which is connected with the shaft 11 through the worm 1%, the worm wheel 15 and sleeve 16, as more fully shown and described in the patent above referred to. T he ratchet wheel is operated by one or the other of two paw s l7 and 18 mounted in the arms of a bell crank lever 19 and arranged on opposite sides of the ratchet wheel, .the pattern cams are rotated in the proper direction for operating upon left shoes, and'when the pawl 18 is in engagement with the ratchet wheel, the pattern cams are driven in the proper direction for operating upon right shoes.

.The pawls are normally held out of engagement with the ratchet wheel by the,

guards, and one or the other of the guards is actuated by the operator, either" in passing from the shank on to the forepart, or at the proper point during the operation upon the forepart of theshoe to start the feed or advance movement of the pattern cam. At the completion of the forward movement of the pattern cam, the active pawl is automatically disengaged from the ratchet, so that the mechanism is relieved from the wear to which it would otherwise be subjected. The automatic disengaging of the pawl at this time also enables the frictional connection between the ratchet wheel and attern cams to be dispensed with if desire The mechanism for operating and controlling the pawls comprises two slide' plates 28 and 29 carrying the guards 22 and 23 respectively, and mounted side by'side in a fixed guideway. The slide plates are connected hy..a spring 30 arranged in grooves formed in the adjacent faces of the slides, one end of the spring being connected to a pin 31 on the; slide 28, and the other end to a pin"32 .111 the slide 29. The spring acts toj holdIhoth-f slides in normal position, with the rearen'd' of the slide 29 in engagement with'dne side of a stop pin 33, and witha in est-s a e FT slide 28 in engagementwith the opposite side of the stop pin, thus holdin" theguar'ds' 22 and 23 in position toretain t er-pawls out of engagement with the ratchet wheel.

' devices through whichfthe operator act'uates the slide plates 28 and 29 comprise a lever 35 provided withapivot stud 36, the axis of which is arranged between two pins 37 and 38 which project laterally from the slides 28 and 29 respectively. The slide 29 .is cut away at 39 for the passa e of the in 37. The lever 35 is provided with a vertical guideway 1n which a pivot block 40 connected with a block 40 is mounted, so that it may be moved into position to engage either the pin 37 or the pin 38. The lever is also provided .with a horizontal arm which ooved 'to receive a pivot block 41 car-' The move either the slide 29 or the slide 28 in a direetion to allow the pawl cont-rolled by it to engage the ratchet wheel. If the block- 40 is in the position indicated in the drawings, when the lever is rocked, the block will engage the pin 37' and draw theslide 28 toward the right, thus throwing the pawl 17 into operation, so that the pattern cams will be advanced in the proper direction for operating upon a left shoe. If the block 40 is in position below the pivotal axis of the lever 35, the block will engage the pin 38, and will move the slide 29 toward the left to throw the awl 18 into operation, so that the patterncams will be advanced in the proper direction for operating upon a right shoe. 5 When the slide 28 is actuated to throw the pawl 17 into operatiomit is held in position againstthe tension of the spring 30 by a latch 45 which is arranged to enga e a notch 46 in the lower edge of theslid e. The pawl 17 will therefore remain in action until the latch 45 is disengaged from the notch 46, so that the slide 28 may return to normal position whereupon the guard 22 disengages the pawl from the ratchet wheel. When-the slide 29 is actuated to throw the pawl 18 into action, it is retained inposition against the tension of the spring 30 by ya latch 47 arranged to engage the side 48 of I; the recess 39, so that the pawl remains in- {actionfuntil the latch-isdisengaged and the slide; returnedto normal position by the spring. The: slide 29 is provided with a notch 49in=its-lower edge arranged to regist er with-ithe'latch 45 when the slide is in normal-*position, and the slide 28 is provided with anotch 50 in its upper edge arranged to register withthe latch 47 when this slide is in its normal position. Whn the latch 45 engages the notch 46 of the slide 28 to holdit in such position that the pawl 17 remains in action, the latch also engages the notch 49'on the slide 29,v and locks it in po-.

'sition to retain the pawl 18 out of action.

The pawl 18 cannot therefore be thrown into action while the pawl 17 is in engagement withthe'ratchet wheel. In a similar manner the latch 47, by engagement with the notch .50, locks the slide 28 in position to retain the pawl 17 out of action when the .latch is in engagement with the shoulder 48, and is holding the slide 29 in such position that the'pawl 18 remains in action. The latches 45 and 47 are arranged one above the other, and in position to be engag-ed and actuated by a lug 51- projecting fio-m the block 40. At the completion of the movement of the pattern cam by the pawl, 17, for instance, the clock 40 is auto matically moved from the position indicated in the drawings to a position at the right of the pin 38 in Fig. 5, so that the nexttime the operator draws down the bar 42 the pawl 18 will be thrown into operation to so that the latch is disengaged from-the slide 28, allowing the spring to return the slide to normal osition, and thus disengage the pawl 17 rom the ratchet wheel. In a similarmanner the movement of the block into position to engage the pin 37 at the completion of the movement of the pattern cam by the pawl 18, disengages the.

latch 47 from the'shde 29, and thus causes the pawl 18 to be disengaged from the ratchet wheel.

The block40 is shifted at the completion of the movement of the pattern cams in either direction by pins 52 and 53 arranged to engage a-lever 54 which is connected to the link 55 on which the block 40 is formed, through the devices shown in Fig. 2, and fully described in the patent above referred to. Thepin's 52 and 53 are adjustably se-' cured to'a disk 56 which is inturn secured to the shaft 11, and turns with the pattern cam.
